If the same user registers separately using an email address and a mobile phone number, two independent accounts will be created, and points, star ratings, activity records, etc., will be recorded separately. Merging related accounts is currently not supported.

Article 3 Events and competitions

3.1 The events and competitions module mainly displays basic information such as the theme, time, location, organizer, and participation method of events or competitions, and such information may be updated in accordance with actual arrangements. If an adjustment affects the material rights and interests of registered users or event arrangements, corresponding arrangements shall be made and users shall be notified in accordance with relevant specific rules and legal provisions.

3.2 Browsing competition information, registering a platform account, or clicking the registration portal does not mean that you have successfully registered, obtained competition qualification, or won an award.

Matters such as competition eligibility, submission of entries, evaluation rules, awards, rights in entries, event modifications, and related disputes shall be handled in accordance with the specific competition terms.

3.3 Competitions may be hosted or co-hosted by us, or independently organized by other entities, subject to the descriptions on the competition page. We will perform corresponding obligations based on the roles we actually assume in the competition; if we only provide competition information or links, we do not thereby become the competition organizer. Before submitting registration materials, please confirm the recipient of the materials and read the corresponding personal information processing instructions.

Article 4 Ecosystem cases

4.1 The ecosystem cases module displays content published by us, such as scenario applications, model practices, robot skills, and development tools. We will use and display such content within the scope of obtained authorization or other legal bases; where third-party works, names, logos, etc., are involved, the relevant rights and interests shall remain with the respective right holders.

Article 5 Simulation evaluation and leaderboards

5.1 The simulation platform tests the performance of models in specified tasks through specific simulation environments, and may conduct benchmark evaluations and leaderboard displays in accordance with relevant rules. You may submit model files or model links through the portals actually opened by the platform; the file formats, interfaces, runtime environments, and resource requirements shall be subject to the descriptions on the submission page.

5.2 You shall obtain the submitted models and related materials through lawful channels, and ensure that you have the right to submit these materials to the platform, entrust the platform to obtain relevant materials, load and run the models, and conduct evaluations, as well as authorize the platform to display relevant information as agreed. If submitting a third-party model, you shall also comply with its license, terms of service, and lawful terms of use; even if a model can be legally downloaded or publicly accessed, it does not mean that you may upload, copy, run, or disseminate it without restriction. Please do not submit trade secrets, personal information, or other restricted materials that you have no right to disclose.

5.3 We will formulate evaluation methods in combination with selected tasks and application scenarios, and make corresponding technical judgments and choices regarding evaluation tasks, metrics, annotation methods, weights, and test conditions. We will formulate evaluation methods and conduct evaluations based on reasonable technical grounds, and explain the main evaluation methods, applicable scope, and rule versions on relevant pages. Platform evaluations cannot cover all capabilities of a model; Unless clearly stated otherwise, platform evaluation standards do not constitute national standards or industry standards, nor do evaluations constitute independent third-party certifications.

5.4 Evaluation scores and rankings only reflect the performance of the submitted model version under the corresponding evaluation rules, simulation environments, configurations, and operating conditions. Evaluation results may be affected by factors such as randomness, data scope, version changes, and operating status, are for technical research and development reference only, cannot be used to judge the overall merits of a model across all scenarios, and cannot serve as a guarantee of the model in terms of real robot deployment, commercial application, or safety performance. Where rule versions or operating conditions differ, evaluation scores may not be directly comparable.

5.5 You shall truthfully fill in the model name, source, version, as well as modifications and configurations that affect the evaluation, and provide explanations for verification when necessary. You shall not impersonate the original author, right holder, or official team of a model, shall not label a modified model as an unmodified original model, and shall not cause evaluation results to be untruthful or misleading through misnaming, concealing key differences, forging records, manipulating rankings, exploiting vulnerabilities, or other means. You shall not intentionally set unreasonable conditions to disparage models of others, or interfere with the evaluation environment through abnormal requests or malicious programs. You may still engage in technical discussions, make reasonable comparisons, or raise substantiated objections based on facts.

5.6 If the evaluation in which you participate involves a public leaderboard, we will explain to you the information intended to be disclosed before you submit the model or confirm your listing. Disclosed information may include model name, source or version description, submitter display name, evaluation task, score, ranking, and evaluation time, subject to the specific prompt at the time. After you confirm participation in the public leaderboard, we may display relevant information within the explained scope. Where the disclosure of personally identifiable information is involved, we will obtain the required separate consent in accordance with the law. Disclosing evaluation results does not mean disclosing model files, model weights, access credentials, or other non-public materials, and the general evaluation authorization under this agreement does not include disclosing such materials.

5.7 If the platform provides an evaluation option visible only to yourself, you may choose to use it in accordance with the instructions on the relevant page. We will handle the evaluation results in accordance with the disclosure scope you select. Without your separate confirmation, we will not use the results of such private evaluation and the relevant non-public materials submitted by you for display on public leaderboards.

5.8 Where models, names, and descriptions on the leaderboard are submitted by users, we will distinguish them in accordance with the relevant display explanations. The inclusion or display of a model does not indicate that it is necessarily submitted by the original author or right holder in person, nor does it indicate that such party endorses the platform evaluation or has a cooperative relationship with the platform. You shall be responsible for the source, naming, authenticity of materials, and submission behavior of the model; We shall bear corresponding responsibilities in accordance with the law for our own evaluation implementation, information display, and error handling. For scores suspected of violations or subject to reasonable disputes, we may request supplementary materials and conduct verification, and mark disputes, suspend display, retest, correct, or remove them as appropriate.

5.9 After you submit the model or relevant materials, the original ownership of rights therein remains unchanged. To complete the evaluation and related services you select, you grant us a non-exclusive license, within the scope of your authorization rights, to obtain, perform storage of, make necessary copies of, load, and run relevant materials and generate evaluation results. The above authorization is limited solely to the purpose and term necessary for providing such service; Where public display is involved, it shall be limited to the scope confirmed by you pursuant to Section 5.6. This authorization does not include using your model files and non-public submitted materials to train or fine-tune other models, or for other purposes unrelated to this service. If such use is needed, we will separately explain the purpose, scope, and conditions, and obtain corresponding legal authorization.

5.10 We will only retain the necessary submitted materials, operation records, and results for the purposes of completing evaluations, providing related result services, ensuring necessary security, and handling disputes that have occurred, and the retention period will not exceed the period necessary for the above purposes. Specific retention arrangements will be explained to you in accordance with the relevant rules. You may apply to delete model files, links, and other submitted materials, or to cease the public display of relevant results, through the contact information listed in Article 15. After verifying that you are entitled to make such an application, we will process it and provide feedback within a reasonable period. Deleting materials or ceasing display may lead to the termination of incomplete evaluations, and relevant results may also become unavailable for further review. If it is indeed necessary to retain necessary records in accordance with the law, we will explain the reasons, restrict their usage and access permissions, and handle them in accordance with the law after the reasons for retention cease to exist. Deleting materials retained by the platform will not simultaneously delete original models saved by you on other websites or content pointed to by the links.

5.11 If you have any objection to the scores, rankings, model naming, or related displays, or believe that relevant content infringes upon your legitimate rights and interests, you may provide the model or task identifier, specific reasons, and relevant evidence in accordance with Article 11. We will verify the situation and, depending on the circumstances, take measures such as review, correction, supplementary explanations, or ceasing display. If evaluation results are affected by rule or system errors, we will reasonably handle the affected results. Where evaluation methods are adjusted due to normal technical updates, we will explain the applicable versions to avoid displaying results under different conditions together without distinction.

5.12 When citing evaluation results externally, you shall accurately state the model version, evaluation rules, evaluation time, and necessary test conditions, and shall not tamper with results, conceal restrictive conditions sufficient to affect others' understanding, or extract partial scores to mislead others, nor shall you claim to have obtained certifications, recommendations, or warranties not actually made by the platform. We will not impose unnecessary restrictions on your truthful and reasonable citations made in accordance with the law.

Article 6 Technical blog components

6.1 The technical blog module mainly provides access portals to our official website, project pages, or code repositories for you to obtain relevant models, software components, and materials. Different resources may be subject to different licenses or terms of use. Please refer to the instructions accompanying the corresponding resources and versions. Resources provided on the same page may also be subject to different licenses.

6.2 When downloading, copying, modifying, distributing, or using technical blog components, you shall comply with the corresponding licenses, including requirements regarding copyright notices, attribution, retaining licenses, providing source code, and other conditions agreed upon in the licenses.

Differences in system versions, hardware, data, third-party dependencies, or configurations may cause actual results to differ from documentation examples.

7.3 You shall determine whether the relevant materials are applicable based on the actual use. Before applying models, code, or related deliverables to real devices or production environments, you shall complete necessary testing and security verification, and comply with the requirements of the devices and use scenarios. Passing simulation tests or successfully running documentation examples does not indicate that the verification required for real deployment has been completed. For express commitments made by us, known errors, and obligations to be performed in accordance with the law, we shall still bear corresponding liabilities.

Article 8 points and related rights and interests

8.1 Platform points are incentive records obtained by you after completing login, registration, event check-in, or other free tasks in accordance with published rules. The specific tasks, reward amounts, trigger conditions, and collection methods for obtaining points shall be subject to the rules of the tasks or events actually available at that time; Whether the same behavior can repeatedly obtain points shall be subject to the corresponding rules.

8.2 Points are not legal tender and do not support top-up, purchase, transfer, sale, withdrawal, or cash redemption. Points are limited to designated uses actually made available by the platform with published rules; After gift redemption, mall deductions, or other rights and interests become available, you may use points in accordance with the corresponding rules. Uses that are not yet available do not mean that you have obtained the rights to the corresponding goods, gifts, or deductions.

8.3 We will specify necessary matters such as specific redemption conditions, required points, available quantities, application and fulfillment methods, applicable terms, and shipping fees before the corresponding redemption or deduction events become available; If a free task has promised specific redemption rights and interests, we will explain the relevant conditions before the task is launched. Where mall transactions are involved, such transactions shall also be subject to the purchase and after-sales rules that have taken effect in accordance with the law. For redemption or transaction rights and interests that have been established in accordance with valid rules, we will not cancel them solely on the basis of this agreement.

8.4 You may not obtain or use points through false task records, batch registration, fraudulent use of others' accounts, repeated collection, exploitation of system vulnerabilities, or other improper means. When abnormal points are found, we may conduct verification based on relevant records and suspend the use of relevant points within the necessary scope; Upon verification, for points that are erroneously credited or obtained in violation of rules, we may correct or cancel them and explain the basis. You have the right to raise objections through feedback channels.

8.5 If the points rules are adjusted, we will give you reasonable notice. If the adjustment has a material adverse effect on points you have already obtained or activities you have participated in, we will arrange necessary transitional measures and rights processing in accordance with the law, and will not retroactively deprive you of your legally acquired rights and interests based on rules not notified in advance. If validity periods of points and expiration handling methods are set, we will clearly explain them before they apply.

8.6 If you have any questions or objections regarding points records, deductions, redemptions, or gift fulfillment, you may contact us through the channels listed in Article 15 and provide information on relevant tasks, points records, or redemption matters. We will verify and handle the matter in accordance with applicable rules and legal provisions.
